	The AC adapter theoretically offers 120W, but it's safer to assume no more than 90W (¾ of the rated output). This will be used to drive our heating elements and fans. The Arduino itself is powered off the AMS circuit. Leaving aside peripherals, it ought not draw more than 125 mA, even when transmitting on wireless. This ought be safe, and is less than our fans were previously drawing from the AMS. Remember, Bambu doesn't guarantee any slack on the AMS circuit, and expressly instructs you not to draw from it.

	The BentoBox is designed to filter out some of the VOCs generated when printing certain materials. It wants two 40mm fans, a HEPA filter, and activated acid-free charcoal (it is claimed that acidful charcoal will fuck up your printer; I don't know anything about it). I had several Delta 40mm screamers free I'd pulled from an [[Aruba_2500-48p\|Aruba switch]] ([[Noctua]] NF-A4s are <b>not</b> strong enough to effectively draw air through the tower, sadly). I tapped into the AMS's 24V circuit using a [https://www.etsy.com/listing/1460463476/bambu-power-tap-v13-kit Power Tap v1.3] (see below). The fans are 12V, so I employed a LMS2596 buck converter to efficiently drop the voltage. The BentoBox only serves to draw air through the filter and charcoal; it doesn't vent to the outside or anything. I'll be changing up the power source for this stack; see below.
